Struct calloop::LoopHandle

pub struct LoopHandle<Data> { /* fields omitted */ }

An handle to an event loop

This handle allows you to insert new sources and idles in this event loop, it can be cloned, and it is possible to insert new sources from within a source callback.

Methods

impl<Data: 'static> LoopHandle<Data>

pub fn insert_source<E: EventSource, F: FnMut(E::Event, &mut Data) + 'static>(
    &self,
    source: E,
    callback: F
) -> Result<Source<E>, InsertError<E>>

Insert an new event source in the loop

The provided callback will be called during the dispatching cycles whenever the associated source generates events, see EventLoop::dispatch(..) for details.

pub fn insert_idle<F: FnOnce(&mut Data) + 'static>(&self, callback: F) -> Idle

Insert an idle callback

This callback will be called during a dispatching cycle when the event loop has finished processing all pending events from the sources and becomes idle.

Trait Implementations

impl<Data> Clone for LoopHandle<Data>

fn clone(&self) -> LoopHandle<Data>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
